Racefuel unleaded vs leaded?

With my new build comming up I will be running a CR:9.0 and agressive timing. I will also be running 50/50 water/meth to compensate on low boost/pump fuel.

 

I will however be needing some high octane race fuel to hit those high numbers, but it seems that unleaded fuels are only made in sub-110 octane versions.

A lot of the US boys run c16 and other leaded fuels, what impact will this have on the motor? Is it just an environmental thing, or are precautions made to compensate for the leaded fuel?
